It can be repaired in a short time, which also helps reduce economic losses due to traffic congestion!
The "K-240" is a diamond-free joint for transverse joints that is installed perpendicular or diagonally to the bridge axis (the direction of vehicle travel). By adopting high-nut anchor bolts, there is no need to chip away concrete during repairs, which prevents noise and debris waste, and also shortens construction time. Additionally, the reduction in time helps to minimize exhaust emissions caused by traffic congestion, thus preserving the living environment in urban areas and the natural environment in suburban areas. 【Features】 ■ Protects the deck ■ Comfortable driving ■ Safe driving ■ Environmentally friendly ■ Cost-saving *For more details, please download the PDF or feel free to contact us.
